engine dying due to electric fan

DesertRat said
The way I read you schematic your system should be fine. The alternator should be wired directly to the battery and the battery directly to the relay.
Something (battery or alternator) would have to be really bad to kill the engine when the fan relay closed. Make sure none of this wiring runs through
your bulkhead connector and recheck your install. Sum-ting-wong------good luck!

thanks DesertRat, did check the routing, and everything is as shown in diagram. but, the 85 (blue) which is designated '12 volt power source' is hooked into the back of the ignition switch. I'm wondering if there is a better place for this, or if it wouldn't matter because of the draw from the fan itself on the battery/alternator?
